Sub-benchmarks
AA-Omniscience Index
AA-Omniscience Index is Artificial Analysis's knowledge-reliability metric. It rewards correct answers, penalizes hallucinations, and does not penalize abstention. Scores range from -100 to 100, where 0 means as many correct as incorrect answers.
OmniScience (non-hallucination rate)
OmniScience variant that reports the non-hallucination rate, defined as one minus the hallucination rate.
What is OmniScience?
OmniScience is a broad scientific knowledge and reasoning benchmark that measures both answer accuracy and non-hallucination (calibrated abstention) across science domains.
OmniScience is a text benchmark evaluating models on knowledge, reasoning, and science tasks. LLM Stats tracks 2 models on this benchmark, scored on a 0–1 scale. The current average is 0.7, with the leader at 0.8.
Compare leaders on the best AI for knowledge, best AI for reasoning and best AI for science leaderboards.
Current leaders
Nemotron 3 Ultra (550B A55B) from NVIDIA currently leads the OmniScience leaderboard with a score of 0.787 across 2 evaluated AI models.
